WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 331,610, dated December 1, 1885. Application filed March 3, 1885. Serial No. 157,663. (No model.)

To all whom it may concern:

Be it known that 1, WM. BUNTING, Jr., of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in ater-Closets; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, making part of this application,

My invention relates to a new and useful improvement in that kind of water-closet in which the construction of the bowl and its connections is such that the excrementitious matter is deposited in a receptacle the entire bottom of which is covered with a body of standing water. In the earlier forms of closets of this type (sometimes called water-surface closets) serious objections existed, arising, mainly, from the facts that only an insufficient water-surface could be obtained and the standing water in the bowl could not be properly discharged and completely replenished. In the latest or most approved forms of this type of closet, however, these serious defects have been partially remedied, but only by the use of complicated and expensive mechanism in the way of means for effecting the quick and complete discharge of the water and soil contained in the bowl, and for permitting the fresh supply of water (or the flushingwater) to refill the bowl to the full extent of the charge of water that was therein contained before the use of the closet.

My invention has for its object to provide for use a closet of the type mentioned which will be perfectly efficient in all its operations, and at the same time exceedingly simple inits construction and comparatively economic of manufacture.

To these main ends and objects my invention consistsin the novel features of construction and improved mode of operation, which will be found hereinafter more fully described, and which will be more particularly pointed out and defined in the claim of this specification.

To enable those skilled in the art to which my invention relates to understand and practice it, I will proceed to more fully describe it, referring by letters to the accompanying drawing, which forms part of this specification, and in which I have shown my inven proved form, but which I make, preferably,of 6

a special construction that need not be particularly described here, since itforms the subjectmatter of a separate application for Let ters Patent by me filed about contemporaneously with this case.

E is the base of the bowl, which in this instance is shown as adapted to be connected (at the plane of the floor-line) with the upper end, 0, of a secondary metallic trap, e the inclined leg of which terminates at or runs into the discharge branch 5, that connects with the main soil-pipe; but, instead of this arrangement, the earthenware portion of the closet may be made with the secondary trap e' integral therewith.

D is a ventilating-tube, connected at the point shown, and employed for the wellknown purpose of permitting a free escape of any gases or foul odors that may rise in the pipe S, andfis a metallic clamping device, 3

by means of which, through the media of securing bolts and nuts at'Nand a rubber packing-ring at O, a perfectly tight joint or con nection is formed between the open base E of the earthenware basin and the upper end or 0 vertical leg 6 of the secondary trap 6 I illustrates the floor of the apartment in which the closet is supposed to be located, and T represents the supply-tank, from which water is furnished, as required, to the closet 5 below through the medium of the supplypipe M, which connects at its upper end with the supply-valve of the tank T and at its lower end with the flushing-rim F of the bowl A, all as shown, and in a manner well known to those familiar with the manufacture and use of watencloset apparatus.

Near the uppermost part of the curved exit-pipe B, and forming an open communi- IOO cation with the interior thereof, is an upwardly-projecting tube, y, with which communicates the lower end of an air-exhaust pipe, Q, the upper end of which is turned over and downwardly and connects with the water-supply pipe M, in a manner and for a purpose to be presently more minutely explained.

P is a pull-handle, by means of which the person using the closet operates the supplyvalve Z) of the tank T through the media of the usual chain or cord, 0 and tank-lever 10, all as clearly shown and easily understood.

Communicating with the supply-pipe near its upper end, and just below the valve b", is a siphon, Z, arranged in a well-known manner and so that whenever the valve 1) shall be lifted from its seat to permit the water contained in the tank to flow into the supplypipe M and then speedily closed (thus cutting off the supply afiorded through the valveopening) the supply to the pipe M will be continued through said siphon until the tank (or, if preferred, a compartment thereof) shall have been emptied either wholly or down to a predetermined level, all after a fashion well understood by those familiar with the siphonform of water-closet-tank apparatus.

As before remarked, and as clearly shown in the drawing, the downwardlybent upper end of the pipe Q communicates with the supply-pipe M at a point a short distance below the upper end of the latter, and the opera tion and effect of this combination of the upper end of the pipe Q with the supply-pipe M may be thus explained: WVhenever the supply of water rushes down the pipe M it acts in its descent past the upper open end of pipe Q to induce an exhaustion or par tial exhaustion of the air contained in said pipe Q, thus creating a partial vacuum in that portion of the interior of the dischargepipe B which lies between the surface of the waterseal at a and that of the water-seal at t, and the creation of this partial vacuum in this manner at the locality mentioned facilitates and expedites the emptying of the bowl A of its contents, and conduces also to a rapid and thorough flushing out of the bowl by the incoming fresh supply or charge of water, since the latter enters the bowl and passes over the bridge at m with an impetus due to the gravity or head of the overflowing Water plus the atmospheric pressure on top of the body of water in the bowl A.

It will be understood that in the operation of the contrivance shown the supply of water furnished to pipe M from the tank Tceases as soon as the contents of the said tank shall have been exhausted down to apoint or level at which the siphon Z begins to take air. The siphon then being broken and the pipe M entirely emptied, the supplemental supply of water necessary to refill the bowl A up to the level seen at a is gradually supplied by means of the wellknown expedient of asmalltube such as seen,for instance, at tthc lower end of which communicates with the supply-pipe M below the seat of valve b", and the upper end of which is connected with the supplynozzle of the ball-cock x, that furnishes the water to replenish the tank every time any water may be taken from it for use in the closet. This tube it acts simply to borrow sufficient water from the cook a: to refill the bowl A'toits normal condition afterthe flushing-out operation and after the atmosphere shall have again filled the pipes Q and M.

At the point where the connecting-tube y ends within the enlarged lower end of pipe Q I arrange a check-valve,H,that opens upwardly. This valve is composed, preferably, of a rubber ball properly seated on the upper end of tube 3 and is designed to perform the important function of keeping the end of tube 1 closed gas-tight at all times except when the air is being exhausted from that portion of the space within B before mentioned, in the manner above explained, thus preventing the possible escape upwardly through pipe Q and thence down through M and into the house, of any foul odors or gases that might be generated between the water-seal in the trap e and that formed in the bowl and upper trap.

Of course the details of this valvular contrivance may be varied at the will of the manufacturer and according to circu mstances without departing from the gist of this part of my invention, so long as there be a valve of some sort opening upwardly and adapted to be opened only when the air is being exhausted from the pipe B, and to close the instant this operation of exhaustion ceases.

Having now so fully explained my invention that those skilled in the art can easily practice it, and wishing it to be understood that either one or the other or both features of'my improvement maybe used with greater or less advantage, what I claim as new, and desire to secure by Letters Patent, is-

In a water-closet provided with a siphon for continuing the supply to the' outlet-pipe of the tank after the supply-valve shall have been closed, and with means for effectinga supplemental supply of water to the upper end of said outlet-pipe after the action of the siphon in emptying the tank shall have ceased, the combination, with these devices, and with the bowl A and that portion of the exit or discharge pipe located between the water-seal of the bowl and the secondary trap beneath the bowl, of a tube, Q, communicating at its lower end with said space in said exit-pipe and having its upper end communicating with the outletpipe of the tank, (at a proper elevatiom) all substantially in the manner and for the purposes set forth.

In witness whereof I have hereunto set my hand this 31st day of January, 1885.
